Do your research kids – this is Chinese junk – the games are knock-offs – re-makes and 95% are home brewed crap. Q Bert, Zaxxon? Nope, only 20 versions of 8 bit hack Marios
If you want the REAL classic games like Zaxxon and Q Bert and Donkey Kong – buy the ColecoVision retro set for about the same money – only you get the real games and graphics.
